1. Use the graph below to answer the following questions. The temperature values in the data set are provided as differences from a mean of 15 degrees C. These data have been analyzed by scientists to show a 0.5 degrees C increase in global temperatures. However, this finding is under dispute because some claim that the amount of error in the data is too large to justify the conclusion. This data set has been created using the following steps: o Data was collected from land based stations, from ocean buoys, and from ships. o For each year data has been averaged to come up with a yearly average. o Data is smoothed to accommodate historical changes that skew the data (e.g., weather stations near cities record artificially high temperatures because create what is called an "urban heat island effect."). State a generalization that interprets this data and incorporates time and temperature from the graph above.
